I composed another new song and always have the same trouble. Is this really a new song or did I unconsciously use parts of songs that I already heard. Sometimes I remember a melody and don't know the title or interpret.

I know that I have the song somewhere in my midi archive but how can
I find it?

This program tries to search midi files for given sequences of some notes. It is better to enter only few notes of different parts of songs, instead of a longer sequence of notes because it is not sure if the midi uses exactly same sequence.
